Laryngeal carcinoma, are mostly squamous cell carcinomas, reflecting their origin from the skin of the larynx. Most laryngeal cancers originate in the glottis. Supraglottic cancers are less common and subglottic tumours are least frequent. Supraglottic cancer is a disease in which malignant (cancer) cells form in the tissues of the larynx. Use of tobacco products and drinking too much alcohol can affect the risk of laryngeal cancer. The complaint of the patient includes a sore throat and ear pain. CT scan of throat and neck are used to help detect, diagnose, and stage laryngeal cancer. Management of the head and neck cancer patient most often will include radiation therapy. The oral complications of head and neck Radiation therapy result from radiation injury to the salivary glands, oral mucosa and taste buds, oral musculature, alveolar bone, and skin. The oral complications of therapy for head and neck cancer can significantly impair quality of life. The oral health care team serves a vital role in the prevention and management of short- and long-term oral complications of cancer treatment. Here I present two cases of supraglottic carcinomawhounderwentoral health care before radiation therapy.
